We perform experiments on six real-world directed network data sets, namely Telegram [1]}, Blog [2]},
Migration [3]}, WikiTalk [4]},
Cora-ML, and CiteSeer [5]},
with more details provided in SI B.3.
We use the first four data sets on node clustering tasks, and the rest for application to node classification and link direction prediction.
We set the number of clusters \(K\)  to be 4, 2, 10, 10, 7, 6, respectively, and values of \(\beta \)  to be 5, 1, 9, 10, 11, 9, respectively.
